Chapter 6,8

Question 1

reactivity series

Answer 1

potassium
sodium
calcium
magnesium
aluminium
(carbon)
zinc
iron
tin
lead
(hydrogen)
copper
silver
gold
platinum

Question 2

what does the reactivity series do

Answer 2

ranks meals according to their reactivities. by doing this, it also predicts how certain simple reactions of metals with oxygen water and acids occur. predictons about more complex reactions can also be made where 1 metal competes with another to displace it. it also predicts the intensity of reactions

Question 3

oxyacid

Answer 3

acid containg oxygen
H2SO4
H3PO4
HNO3
H2NO3

Question 4

reaction of metals and oxygen

Answer 4

metal + oxugen –> metal oxide

Question 5

reaction of metals and water

Answer 5

metal + water –> metal hydroxide + hydrogen

Question 6

reaction of metals and acids

Answer 6

metal + acid –> salt + hydrogen

Question 7

reactivity

Answer 7

how readily elements take part in reactions with other chemicals

Question 8

redox reaction

Answer 8

involves the transfer of electrons between 2 chemical substances, 1 willing to accept them (reduced) and one wiing to donate them (oxidized)

Question 9

oxidation

Answer 9

loses electrons
anything that gets oxidised is a reducing agent
anything getting oxidised increases in O.N

Question 10

reduction

Answer 10

gains electrons
anything that gets reduced is an oxidising agent
anything getting reduced decreases in O.N
